Mrs. Gargantua thinks she finally may have found
a medicine which will remove the blackness from
her teeth. But first she has to mix a liquid
containing 4% reactor fuel with a liquid containing
20% reactor fuel to create a 6 ounce liquid
containing 8% reactor fuel. How many ounces of
the 4% liquid must she use? Round your answer to
the nearest one decimal place (tenths).
Answer:
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
Step-by-step explanation:
x = amount of 4% fuel
6 - x = amount of 20% fuel
0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals
4x + 20(6 - x) = 8(6)
4x + 120 - 20x = 48
-16x + 120 = 48
-16x = -72
x = 4.5
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

The population of Renton, WA, is about 101920
people.
Ten years ago, the population was about 91000
people.
By what percent did the population increase
between ten years ago and now?
Answer:
Step-by-step explanation:
%change=100(final-initial)/(initial)
%change=100(101920-91000)/(91000)
%change=12%
A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
A TV that usually sells for $170.09 is on sale for 15% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Find the discounted price: 15% off of 170.09
Discounted Price = 170.09 * (1 - 0.15) <-- 15% as a decimal is 0.15, and 1 is 100%. So, we subtract to get 85% of the original price.
Discounted Price =170.09(0.85)
Discounted Price = $144
Now, add in the sales tax of 6% to the Discounted Price.
Price after sales tax = Discounted Price * 1.06
Price after sales tax = $144 * 1.06
Price after sales tax = $152.64
what's the distance between (6, 4) and (2, 1)
Answer:
5
Step-by-step explanation:
You will need the distance formula. [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\[/tex]
([tex]x_{1}[/tex], [tex]y_{1}[/tex]) ([tex]x_{2}[/tex], [tex]y_{2}[/tex])
Now plug in the two points into the distance formula.
d= [tex]\sqrt{(2-6)^{2}+(1-4)^{2} }[/tex]
d= 5
Find sin A, cos A, and tan A as
a fraction in simplest form.
Answer:
sin A = [tex]\frac{15}{17}[/tex]
cos A = [tex]\frac{8}{17}[/tex]
tan A = [tex]1\frac{7}{8}[/tex]
Step-by-step explanation:
sine = [tex]\frac{ooposite}{hypothenuse}[/tex]
sine A = [tex]\frac{15}{17}[/tex]
cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]
cos A = [tex]\frac{8}{17}[/tex]
tan = [tex]\frac{opposite}{adjacent}[/tex]
tan A = [tex]\frac{15}{8} = 1\frac{7}{8}[/tex]

Hello
I need to figure out this equation for homework and I don't understand how you get the answer.
(5y^2)^-2
Answer:
it can be taken like this
5 y^2/2= 2.5 y^2
any chance someone can explain this ?
Answer:
(-9, 5)
Step-by-step explanation:
there are 2 variable: x and y
eliminate one of the variables for example y
-x - y = 4
-2x - y = 13 multiply this equation by (-1)
-x - y = 4
2x + y = -13
add both equations
2x-x-y+y = 4-13
x = -9
substitute x = -9 in the first equation
-(-9)-y = 4
9 - y = 4 subtract 9 from both sides
-y = 4 - 9
-y = -5 multiply by (-1)
y = 5

Question
The data in this question will be utilized for the next three questions. The number of pets a group of students has, are given below.
Number of pets: 0-2 2-4 4-6 6-8 8-10 10-12 12-14
Number of students: 1 2 1 5 6 2 3
Calculate
(1) Mean (2) Sample Variance (3) Sample Standard Deviation
Answer:
[tex](1)[/tex] [tex]\bar x = 8.1[/tex]
[tex](2)[/tex] [tex]\sigma^2 = 6.341[/tex]
[tex](3)[/tex] [tex]\sigma = 2.518[/tex]
Step-by-step explanation:
Given
The above data
First, we calculate the class midpoint (x)
Pets: [tex]0-2[/tex] [tex]2-4[/tex] [tex]4-6[/tex] [tex]6-8[/tex] [tex]8-10[/tex] [tex]10-12[/tex] [tex]12-14[/tex]
x 1 3 5 7 9 11 13
f: 1 2 1 5 6 2 3
The class midpoint (x) is calculated by the average of each group.
For pets: 0 - 2.
[tex]x = \frac{0 + 2}{2}= \frac{2}{2} = 1[/tex]
The same is done for other groups.
Solving (a): Mean
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
This gives:
[tex]\bar x = \frac{1 * 1 + 3 * 2 + 5 * 1 + 7 * 5 + 9 * 6 + 11 * 2 + 13 * 3}{1 + 2 + 1 + 5 + 6 + 2 + 3}[/tex]
[tex]\bar x = \frac{162}{20}[/tex]
[tex]\bar x = 8.1[/tex]
Solving (b): Sample Variance
This is calculated as:
[tex]\sigma^2 = \frac{\sum(x_i - \bar x)^2}{\sum f - 1}[/tex]
So:
[tex]\sigma^2 = \frac{(1 - 8.1)^2+(3 - 8.1)^2+(5 - 8.1)^2+(7 - 8.1)^2+(9 - 8.1)^2+(11 - 8.1)^2+(13 - 8.1)^2}{20 - 1}[/tex]
[tex]\sigma^2 = \frac{120.47}{19}[/tex]
[tex]\sigma^2 = 6.341[/tex]
Solving (c): The sample standard deviation
This is calculated as:
[tex]\sigma = \sqrt{\sigma^2[/tex]
[tex]\sigma = \sqrt{6.341[/tex]
[tex]\sigma = 2.518[/tex]
Solve: 2 ( X + 5 ) = 3X + 1 Show your work
Answer:
x = 9
Step-by-step explanation:
Given
2(x + 5) = 3x + 1 ← distribute left side
2x + 10 = 3x + 1 ( subtract 2x from both sides )
10 = x + 1 ( subtract 1 from both sides )
9 = x

Simplify this expression. 2 square root 5 (13 + square root 2)
Answer:
i'm assuming it's 2*√5(13+√2) so 2√10+26√5
Step-by-step explanation:
The product of 2 square root 5 (13 + square root 2) in simplified form is 26√5 + 2√10
Calculating the product in simplified formFrom the question, we have the following parameters that can be used in our computation:
2 square root 5 (13 + square root 2)
Express as products
So, we have
2√5 * (13 + √2)
Open the brackets
So, we have
2√5 * (13 + √2) = 2√5 * 13 + 2√5 *√2
Multiply the radicands
So, we have the following
2√5 * (13 + √2) = 2√5 * 13 + 2√10
Evaluate the products
So, we have the following
2√5 * (13 + √2) = 26√5 + 2√10
Hence, the solution is 26√5 + 2√10
